INKED RIBBON WITH-UNINKED END Filed June 9, 1934 INVENTOR PHILIP MANNING BY C? ATTORNEY Patented Nov. 5, 1935 UNITED STATES PATENT OFFICE 2,020,152 mxen RIBBON wrrn UNINKED END Philip Mannino, Brooklyn, N. Y. Application June 9, 1934, Serial No. 729,932 40min (c1. 197-172) This invention relates to new and useful improvements in an inked ribbon with an uninked rangement of an inked ribbon wound upon a spool 1 X or core and provided with an uninked outer end.

The purpose of the uninked outer end isto afford a clean handling portion when the ribbon is set upon a machine. Prior to this invention ribbons have been made with uninked portions at- 15 tached upon the ends. Such constructions are interior to the instant invention in that they are more expensive to manufacture and the attachment of the uninked portions with inked portions very often interferes with the'proper operation of the machine upon which it is engaged.

The invention also proposes to teach a method for manufacturing the inked ribbon with an uninked outer end so as to be adaptable for one color or multi-color ribbons of any desired lengths.

Another one of the objects of this invention is an arrangement associated with the uninked end of the ribbon and a spool upon which it is engaged, for preventing ink from the inked portion travelling through and partially inking or soil- 30 ing the uninked portion.

. Still further the invention proposes the provision of a foreign strip of ink proof material wound into the turns of the inked ribbon with the uninked end and'arranged at the uninked end 'portion in such a. manner so as to separate the inked from the uninked portions. I

Still further the invention proposes another method for protecting the uninked portion from the inked portion which is characterized by the 40 provision of ink proof material impregnated at a portion of the-uninked portion of the ribbon so as to separate the inked from the uninked portions.

Still further the invention proposes the construction of an article as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and. advantages thereof, reference will be had to the following description and. accompanying drawing, and to the appended claims in which the various novel features of the invenas wax, paper or similar material is associated r In the accompanying drawing forming a material part of this disclosure:-

Ffig. 1 isa perspective view of a spool with an a manner but the uninked portion I I -must be pro-' tected from the application of the ink to remain inked ribbon having an uninked outer end according to this invention.

Fig. 2 is a horizontal sectional view of a ribbon constructed accordingto this invention similar to the ribbon shown in Fig. 1 except arranged according to another embodiment of this invention.

Fig. 3 is a perspective view of-ink proof material used in Fig. 2.

Fig. 4 is a fragmentary clcvational view of an inked ribbon with uninked end constructed 110- cording to another embodiment of this invention.

The inked, ribbon with an outer uninked end according to this invention is shown associated upon a spool l0 generally used in typewriters and other similar types of machines.

This spool II] is adapted to be engaged upon a 1 receiving mandrel, spindle or shaft of the type writer or adding machine or other machine as is generally known in the art and for this reason further specific details thereof will not be given. An inked ribbon H is wound upon the spool l0 and is provided with an uninked outer end It. The inner end of the ribbon is attached upon the spool in a conventionalamanner generally known and for this reason not described in detail in this specification.

The line ll is the junction between the inked and uninked portions of the ribbon. The ribbon may be supplied with ink in any conventional nni nked. It is a feature of thc invention that 'gthe inked and uninked portions are integral, con- .trasted with prior arrangementswhere uninked portions were attached upon the ends of an inked ribbon. It is a feature of this invention when the ribbon illustrated in Fig. 1 is engaged upon a machine the uninked outer end may be handled any number of times without the fingers becoming dirty with ink as would happen if the entire ribbon were inked.

In Figs. 2 and 3 another embodiment of the invention has been disclosed wherein provision is made for protecting the uninked end-from the ink of the inked portion of the ribbon. More particularly an ink proof strip of material l2 such as wax paper, or similar material is associated with the ribbon in a peculiar manner to function as a protection. More specifically, the protecting strip I2 is wound between the turns of the ribbon and extends partially over the inked and uninked portions so that there is at least a full turn of the protector l2 to-separate the inked end from the uninked portion of the ribbon.

This is clearly illustrated in Fig. 2 where the .cated by reference numeral I2 ink proof material 2 removed. Then the'ribbon.

is applied in the ordinary fashion. A feature of this invention lies in the fact that the uninked portion will be perfectly clean since it was separated from the inked portion.

In Fig. 4 another embodiment of the invention has been disclosed wherein an inked ribbon II is illustrated provided with an uninked portion II which is separated from the inked portion by an ink proof material I impregnated into the uninked portion of the ribbon. This ink proof material It may be shellac or some compound of shellac or other materials which would prevent the passage of i2 and protect the uninked portion from the inked portion. The ink proof material i4 is arranged upon the end of the uninked portion ll immediately adJacent the ink portion l I and extends for a suitable distance so as to extend at least one turn around the inked portion when the ribbon is on a spool and so thoroughly separate the inked fromthe uninked portions.

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

' 1. A ribbon for typewriters, adding machines and the like, comprising a strip of ribbon material having a portion impregnated with ink 5 and having a second portion at one end free of ink, a part of the uninked portion adjacent to the inked portion being covered with an ink proof material for a distance at least as long as the circumference of said inked portion when the latter is rolled upon a typewriter reel.

2. A ribbon for typewriters, adding machines and the like, comprising a strip of ribbon material having a, portion impregnated with ink and having a second portion at one end free of ink, said latter portion being substantially equal to twice the circumference of said ribbon when rolled, the inner half of said second portion being covered with an ink proof material.

3. A ribbon for typewriters, adding machines 90 and the like, comprising a strip of ribbon material impregnated with ink from the inner end to a short distance from the outer end and ink proof means upon the inner portion of the uninked portion to cover the inked portion whereby as the outer end of the uninked portion will be held away from the inked portion and protected from receiving ink when the ribbon is rolled.

4. A ribbon for typewriters, adding machines and the like, comprising a strip of ribbon material' having the greater portion impregnated with ink and having the lesser portion at one end free of ink, said lesser portion being at least as long as twice the circumference of the inked portion when rolled and said lesser portion having an inner portion and an outer portion equal in length, the said inner portion being impregnated with ink proof material to protect the outer portion from ink.
